Abstract: An ejection device (11) for compound-containing containers (6) has a receptacle (12) for the container (6) and two piston rods (21) having a pressure transmitting element (23) at its end (22) facing the receptacle (12). The ejection device (11) also has a displacement unit (31) for displacing the piston rods (21) in direction of the receptacle (12) and includes a drive (41) and a displacement device (51) having a retraction element (52), and the drive (41) having a drum unit (61) with a rotating member (62) for the retraction element (52). The retraction element (52), is secured, on one hand, in a region of an end (24) of the piston rods (21) remote of the receptacle (12) and, on the other hand, is wound onto the rotating member (62) of the drum unit (61).

Abstract: An ejection device (11) for containers (36) containing compounds has an ejection unit (12) and a receiving chamber (16) for the container (36) and which is defined on, one side, by the ejection unit (12) and on the other side, by a front plate (26) which is arranged at a distance from the ejection unit (12). The front plate (26) is pivotable around a pivot point (28) defining a pivot axis (27) from an open position in which the container (36) can be inserted into the receiving chamber (16), to a closed position in which the container (36) is held in the receiving chamber (16). A snap lock with flexible snap-in member (31) and a rigid holding member (29) is provided at a distance from the pivot point (28) on the front plate (26) for locking the front plate (26) in the closed position and cooperating with snap receptacle (22) arranged at the ejection device (11) for receiving the snap-in member (31).

Abstract: An ejection device (11) has an ejection unit (12) having a displacement mechanism with two piston rods (13), a receptacle unit (32) including receptacle (34) for a container (33), a head part for limiting the receptacle (34) at one of its ends, a holding device (21) which is arranged on the ejection unit (12) for securing the receptacle unit (32) thereto, and tension members (38) provided on the receptacle unit (32) and which extend along the receptacle (34) and are secured to the head part (35), each tension member (38) having a engageable-from behind section (39) at its end remote of the head part, the holding device (21) having locking elements which can engage the engageable-from behind sections (39) of the tension members (38) to lock the receptacle unit (32) with the ejection unit (12).
